There are 15 electrodes in the TruLine ISE series, with each electrode measuring the effective ion concentration of a different ionic species. This provides our customer with a wide range of ISEs to choose from.

Each TruLine ISE features an integrated reference. This eliminates the need for a separate reference half-cell when measuring ion concentration and is more convenient. Each ISE can be refilled with reference/electrode filling solution, extending the life of each ISE. The electrodes also feature a double-junction reference for optimum performance in the lab.
